>Which parts do they produce for Sachs?
I don't know about the frame and other components, but Tomos produces the
single speed automatic 50 cc engine for Sachs, which even released a moped
Prima 2 in 1998, which was basically a Tomos A4 frame single seater with
this engine. See pic at http://twowheelers.tripod.com/SachsPrima2.jpg .
Great thing for someone who loves single speed. And here's some interesting
parts from TOMOS Components catalogue I was talking about:
